HI, just been trying this with Win64_11gRC2 and as soon as I get to step 6, if I select ‘Desktop’ the install just bombs out. No error, no message, no logs (from what I can see), just the window vanishes and that’s it. If I select Server it gets further, but then crashes out when I get to ‘Typical Installation’.
Are there any logs that you know of that might give me some info about this?

I had this issue too. My OS is 64 bit and I downloaded the 64 bit Oracle 11g R2. I freezes when I select “Desktop” and hit next, never advancing to the next step. I’ve tried this several times with the same result. My system meets all the requirements.
